Recent studies have indicated that birth weight to placental weight (BW/PW) ratio is related to perinatal outcomes, but the effect of congenital abnormalities on BW/PW ratio remains unclear. We performed this study to elucidate correlations between BW/PW ratio and congenital abnormalities. Subjects were 735 singleton infants born at 34–41 weeks of gestation admitted to our center between 2010 and 2016. Of these, 109 infants (15%) showed major congenital anomalies. Major congenital anomalies and subgroups were diagnosed according to European Surveillance of Congenital Anomalies criteria. The primary outcome was the association between BW/PW ratio and major congenital anomaly, and secondary outcomes were the distribution pattern of BW/PW ratio with major anomalies and by major anomaly subgroups in each categorization (<10th percentile, 10–90th percentile, or >90th percentile) of BW/PW ratio. BW/PW ratio was not associated (P = 0.20) with presence (adjusted mean BWPW ratio = 5.02, 95% confidence interval [CI] 4.87–5.18) or absence (adjusted mean BW/PW ratio = 4.91, 95%CI 4.85–4.97) of major anomalies, after adjusting for gestational age and sex. Proportions of infants with major anomalies according to BW/PW ratio categories were as follows: 12% in <10th percentile, 15% in 10–90th percentile, and 25% in >90th percentile of BW/PW ratio. Among major anomalies of the nervous system, congenital heart defects, and orofacial clefts, BW/PW ratio showed equally distributed trend across the three BW/PW ratio categories, but showed unequally distributed trend for anomalies of the digestive system, other anomalies/syndromes, or chromosomal abnormalities. BW/PW ratio was not associated with major congenital anomaly, and was distributed diffusely according to major anomaly subgroups. Major anomalies may tend to aggregate in the 90th percentile of the BW/PW ratio.

Addition
As the 1990s, scientists have been finding placental weight (PW), and have reported connectivity anywhere between PW and you may perinatal effects [1,2] and the growth of diseases inside mature life . Eutherian (placental) animals let you know an almost matchmaking anywhere between PW and you will fetal growth, together with complete-identity beginning weight (BW) out of individuals, pigs and you will goats is roughly five times the latest PW [4–6]. Individual PWs and full-term BWs will vary by over 15% ranging from different events otherwise countries [4,seven,8]. But not, an entire-term BW-to-PW (BW/PW) ratio has been proven to simply differ of the below 5% anywhere between ethnicities or country out-of beginning [4,seven,9]. This suggests your BW/PW ratio can offer an invaluable in the world perinatal list. A fairly highest BW/PW proportion ways shortage of placental outdoors likewise have to your fetus. However, a reduced BW/PW ratio ways a good suboptimal fetal position. Earlier research has demonstrated connectivity from BW/PW proportion that have perinatal consequences , chance of intellectual palsy and you may state effects when you look at the after that adulthood . Even when congenital defects make a difference to fetal development , the fresh organization between congenital defects and PW features yet as elucidated [fourteen,15]. We hypothesized you to fetal congenital anomaly may lead to a decreased BW/PW proportion on account of fetal progress restriction, or even to a high BW/PW ratio on account of incorrect fetal over growing. I investigated whether contacts stayed between BW/PW proportion and you can major congenital anomalies therefore the biggest anomaly subgroups.
